David,
I would like to add my compliments and congratulations. Beside being impressed by your work, I also like the Mariner Blue.
Are you looking for insurance to drive the truck anywhere/anytime for any purpose? If so, have you checked with you insurance agent - my State Farm agent now seems able to do this.
If you want collectors' insurance for driving to shows, etc (and minor incidental driving), and you have a locked garage, and all driver/members of you family have another insured vehicle, check with
Hagerty.
Good luck,
